Ishikawa

The Ishikawa clan was a samurai clan of Heian Empire-era Japan.

History
The Ishikawa of Kawachi Province were a weak clan with meagre prosperity, but were peaceful and dependable. Claiming descent from Seiwa's branch of the Minamoto, the Ishikawa clan were allies of the Kamakura Minamoto during the Gempei Wars (in exchange for Minamoto Chikamoto) and assisted them by capturing Kyoto from the Fukuhara Taira in Winter 1182.
